dtmmdbbookgettablist

DtMmdbBookGetTabList(library call)										DtMmdbBookGetTabList(library call)

NAME

       DtMmdbBookGetTabList -- obtains the list of tab sections in a book

SYNOPSIS

       #include <DtMmdb.h>
       DtMmdbHandle** DtMmdbBookGetTabList(
       DtMmdbInfoRequest* request,
       unsigned int* length);

DESCRIPTION

       The  DtMmdbBookGetTabList function returns the list of tab sections for the specified book object. It returns the list in a NULL-terminated
       array. Use the DtMmdbFreeHandleList function to release the memory when the array is no longer needed. Table lookup is  involved  when  the
       identifier is specified by either the primary_oid or sequence_num field.

ARGUMENTS

       request	 Specifies  the  bookcase in the bookcase descriptor field, as well as a valid value in the primary_oid, the secondary_oid, or the
		 sequence_num field.  The primary_oid represents the DtInfo Database object identifier of the TOC section; the secondary_oid  rep-
		 resents  the  object  identifier  of  the book itself; and the sequence_num represents the sequence number of the book within the
		 bookcase (0 based).  If more than one of these fields have a valid value, the order of precedence is: primary_oid, secondary_oid,
		 and, last, sequence_num.

       length	 Specifies the variable to receive the length of the returned list of sections, if the returned pointer to the list is not NULL.

RETURN VALUE

       If  DtMmdbBookGetTabList  completes successfully, it returns a pointer to the list of sections for the book. If it fails, it returns a NULL
       pointer.

EXAMPLE

       None.
